Potassium Permanganate Colour Change - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=OLUyeC...
NOTE FROM THE PROFESSOR: The colour change is caused by the purple permanaganate ions [MnO4]- gaining electrons to form colourless Mn(+2) ions. The oxygen from the permanganate and the H2O2 are converted to H2O and O2 (which bubbles off). The extra H atoms come from the sulphuric acid H2SO4. Both the K and Mn end up as sulfates.
